It's been a while since we had a crazy critter here - although we did see some bizarre plants on Saturday.
This new species of frogfish uses its leg like pectoral fins to crawl - that is when it isn't bouncing around like a rubber ball. See yesterdays University of Washington press release for information and some great photos and video.
Members of Histiophryne psychedelica, or H. psychedelica, don't so much swim as hop. Each time they strike the seafloor they use their fins to push off and they expel water from tiny gill openings on their sides to jet themselves forward. With tails curled tightly to one side --which surely limits their ability to steer -- they look like inflated rubber balls bouncing hither and thither.
